From the Problem Description: "When responding to incidents, emergency responders often interact with individuals who speak little or no English, making it very challenging to quickly assess and respond to the problem. In addition, 9-1-1 dispatchers sometimes struggle with understanding non-English speakers when answering emergency calls. Further, there are times when dispatchers or responders cannot determine which language is being spoken or understand what is being said. The inability of on-scene responders and 9-1-1 dispatchers to effectively communicate in real time with non-English speakers or the speech impaired delays response time, which impacts operations when responding to incidents."
